Loads a page from the session history, identified by its relative location to the current page, for example -1 for the previous page or 1 for the next page. If you specify an out-of-bounds value (for instance, specifying -1 when there are no previously-visited pages in the session history), this method silently has no effect. Calling go() without parameters or a value of 0 reloads the current page. Internet Explorer lets you also specify a string to go to a specific page in the history list.

Pushes the given data onto the session history stack with the specified title and, if provided, URL. The data is treated as opaque by the DOM; you may specify any JavaScript object that can be serialized. Note that Firefox currently ignores the title parameter; for more information, see manipulating the browser history.

Updates the most recent entry on the history stack to have the specified data, title, and, if provided, URL. The data is treated as opaque by the DOM; you may specify any JavaScript object that can be serialized. Note that Firefox currently ignores the title parameter; for more information, see manipulating the browser history.

[1] In Firefox 2 through 5, the passed object is serialized using JSON. Starting in Firefox 6, the object is serialized using the structured clone algorithm. This allows a wider variety of objects to be safely passed.
